6-2-0
In the Whyte notation, a 6-2-0 is a railroad steam locomotive that has an unpowered three-axle leading truck followed by a single powered driving axle. This wheel arrangement is associated with the Crampton locomotive type, and in the USA the single class were sometimes referred to as ''Cramptons''. Other equivalent classifications are: UIC classification: 3A (also known as German classification and Italian classification) French classification: 310 Turkish classification: 14 Swiss classification: 1/4 History The 6-2-0 was a most unusual wheel arrangement, where the bulk of the locomotive's weight was on the unpowered leading wheels rather than the powered driving wheels, therefore giving poor adhesion. The type was only practicable on the Crampton locomotive with a low boiler and large driving wheels placed behind the firebox. United Kingdom The only British 6-2-0 was the locomotive ''Liverpool'' built in 1848 by Bury, Curtis, and Kennedy for the London and North Western Rail ...

Crampton Locomotive
A Crampton locomotive is a type of steam locomotive designed by Thomas Russell Crampton and built by various firms from 1846. The main British builders were Tulk and Ley and Robert Stephenson and Company. Notable features were a low boiler and large driving wheels. The crux of the Crampton patent was that the single driving axle was placed behind the firebox, so that the driving wheels could be very large. This helped to give this design a low centre of gravity, so that it did not require a very broad-gauge track to travel safely at high speeds. Its wheel arrangement was usually or . Design variations Because the single driving axle was behind the firebox, Crampton locomotives usually had outside cylinders. However, some inside cylinder versions were built using indirect drive, then known as a ''jackshaft''. The inside cylinders drove a crankshaft located in front of the firebox and the crankshaft was connected to the driving wheels by outside rods. Some long-wheelb ...

Isaac Dripps
Isaac Dripps (April 17, 1810 – December 28, 1892) was an American machinist and inventor. He worked on the locomotive ''John Bull'' and built seven locomotives. Dripps was a superintendent and partner of various railroad machinery shops. He has several patents to his name. Early life Dripps was born in Belfast, Ireland on April 17, 1810. He came to the United States with his parents when a child. The family settled in Philadelphia. Career Dripps became a machinist apprentice to steamboat machinery manufacturer Thomas Holloway of Philadelphia in 1826 at the age of sixteen. He became a foreman there when he was twenty years old in 1830. He was in charge of extensive repairs to the ''USS Swan'' in New York harbor in 1831 when he was twenty-one years old. Dripps then was enticed by Robert Lewis Stevens, president of Camden & Amboy Railroad, to work for them. He was employed there from 1831–1853. He worked on the locomotive "John Bull" during that time. In the fall of 183 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whyte Notation
Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives (in the latter case also for diesel and electric locomotives), but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers being separated by dashes. For example, a locomotive with two lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bury, Curtis, And Kennedy
Bury, Curtis and Kennedy was a steam locomotive manufacturer in Liverpool, England. Edward Bury established the works in 1826, under the name Edward Bury and Company. He employed James Kennedy as foreman; Kennedy later became a partner. About 1828, the firm moved to bigger premises in Love Lane, Liverpool, known as the Clarence Foundry. Locomotives Their first engine was built in 1830. Called ''Dreadnought'', it ran on the Liverpool and Manchester Railway. It was objected to because it was on six wheels and was sold to the Bolton & Leigh Railway. The second, the four-coupled ''Liverpool'', later in 1830, used a cranked driving axle, and was also objected to (by George Stephenson) because the 6 ft diameter wheels were too big. The Bury type However, they refined their designs and the resulting and locomotives quickly became a standard which was emulated by many other manufacturers, becoming known as the "Bury type".

Leading Wheel
The leading wheel or leading axle or pilot wheel of a steam locomotive is an unpowered wheel or axle located in front of the driving wheels. The axle or axles of the leading wheels are normally located on a leading truck. Leading wheels are used to help the locomotive negotiate curves and to support the front portion of the boiler. Overview Importantly, the leading bogie does not have simple rotational motion about a vertical pivot, as might first be thought. It must also be free to slip sideways to a small extent, otherwise the locomotive is unable to follow curves accurately, and some kind of springing mechanism is normally included to control that movement and provide a tendency to return to centre. A sliding bogie of that type was patented by William Adams in 1865. The first use of leading wheels is commonly attributed to John B. Jervis, who employed them in his 1832 design for a locomotive with four leading wheels and two driving wheels (a type that became known as the ' ...

Wheel Arrangement
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. Major notation schemes The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC class ...

London And North Western Railway
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the L&NWR was the largest joint stock company in the United Kingdom. In 1923, it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line. History The company was formed on 16 July 1846 by the amalgamation of the Grand Junction Railway, London and Birmingham Railway and the Manchester and Birmingham Railway. This move was prompted, in part, by the Great Western Railway's plans for a railway north from Oxford to Birmingham. The company initially had a network of approximately , connecting London with Birmingham, Crewe, Chester, Liverpool and Manchester. The headquarters were at Euston railway station. As traffic increased, it was greatly expanded with the opening in 1849 of the Great Hall, design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR S1
The Pennsylvania Railroad, PRR S1 class steam locomotive (nicknamed "The Big Engine") was a single experimental duplex locomotive of the Pennsylvania Railroad. It was designed to demonstrate the advantages of duplex drives espoused by Baldwin Chief Engineer Ralph P. Johnson. It was the longest and heaviest rigid frame reciprocating steam locomotive that was ever built. The streamliner, streamlined Art Deco styled shell of the locomotive was designed by Raymond Loewy. The S1 had a unique 6-4-4-6 wheel arrangement, meaning that it had two pairs of cylinder (engine), cylinders, each driving two pairs of driving wheels. To achieve stability at fast passenger train speeds (above 100 mph), articulation was not used. The S1 was completed on January 31, 1939, at Altoona shop, and was numbered 6100. At overall, engine and tender, the S1 was the longest reciprocating steam locomotive ever; it also had the heaviest tender (451,840 lb / 205 tonnes), highest tractive effort () of a ...

Anthracite Coal
Anthracite, also known as hard coal, and black coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 97%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. The Coal Region of northeastern P ...
